LATERAIJ GEAR-DRIVE FOR TRAVEL-INDICATORS.

Application filed June 28, 1916.

To all whom it may concern:

Be it known that I, Josnrn Bic-no, a citizen of the United States, residing at Chicago, in the county of (look and State of Illinois, have inventodnew and useful Innirovements in Lateral. Gcar-Drives for TlflVtEl IlltillCfl tors, of which the following a specification, reference being had to the accompany ing drawings, forming a part thereof.

The purpose of this invention is to pro-- vide an improved device for transmittingdriving power for operating a travel indi- Carter on. an automobile from. a powewtrans mission shaft of the vehiole-propelling train.

It consists in the elements and features of construction shown. and described as indicated in the claims.

In the drawings:Figure 1. is a side elevation of a portion of the gear transmission housing which with the transmission shaft protruding therefrom isprovided with devices constituting this invention. Fig. 2 is a section at the line, 22, on Fig. 1. Fig. 3 is a section at the line, 3-43, on Fig. .2.

The gear transmission housing, A, is of a familiar type and design common to many automobile propelling trains having apower-transniitting shaft, B, journaled in it.

Said housing has the shaft protruding from it, and provided on the protruding portion with a flanged coupling, C, for connecting it with a further continuation of said shaft,

usually the propeller shaft, not shown. In

the customary constructioi'i of these parts, the coupling, (1, comprises: the sleeve or hub, C, which is adapted :fordriving connection with, the shaft, 13, as, by having a. square opening to engage the squared end of said shaft, there being a short space on the protruding'portion of said shaft back of said coupling sleeve for a stop collar made fast on the shaft to abut against the inner ball race of the ball bearing shown. at I). In the present construction such stop collar is removed and the interval on said shaft, B, between the inn!" and of the hub or sleeve, C of the coupling. 0, and the bearing is occupied by a gear, E, pressed or keyed fast onto the shaft before the coupling-is applied thereto. This gear for particular purpose for which it is required is a spiral, worm gear as illustrated; and it the space between the bearing and the coupling, C, be morefthan is required for the gear proper,

Serial No. 106,378.

said gear may be provided with a hub or sleeve terminal E coin iletin the occuprovided with an entrance, F, into the cav-.

ity j", of said supplemental housing in which the gear, E, is inclosed, and in said entrance there is journaied a shaft, G, sleeve, H, being providd and screwed into said" en. trance, which is threaded at the outer end -for that purpose, for so journaling the shaft in said entrance. At the inner end of the sleeve journalbearin H, a gear pinion, G, is fast on the shaft, ii, and meshes with the gear, E, said gear pinion being of the spiral type to properly cooperate with said Worm or spiral gear, E, The outer end of the shaft, G, is adapted for driving engagement with. a flexible shaft in the famil. journal. hearing or sleeve, H, lacing similarly provided for connection with the housing of such ficnihle shaft, as indicated loy the exterior thread, hfl thereon. The device is thus adapted for connection with .it of a shaft by which driving power; may be trans mitted to an odometer, speedometer or other travel-indicating device which may be mounted at any convenient point upon the vehicle and is not shown.

.It will be understood that the supplemental housing, F, is designed to'contain lubriicanlt for lubricating the intermeshing gears, E and G and for properly applying the lubricant said supplemental housing 1s M13? way, the

lit

portion of said shaft back of the coupling;

a supplemental housing member secured to the main gear housing and inclosin said gear, said supplemental housing having a lateral entrance to the cavity in which the gear is inclosed; a bearing sleeve intruded through said entrance and made fast therein; a shaft journaled in said sleeve bearing, and a gear on the inner end of said shaft meshing with the gear in the supplemental housing.

2. In combination with a power transimitting shaft, a gear housing in which it is journaled and from which it protrudes and a coupling fast on the protruding end of said shaft, a gear fast on the protruding 'portion of the shaft back of the coupling, a supplemental housing secured to the main.

, gear housin and inclosing said gear, said supplementa housing having a lateral entrance leading into the housing cavity, a shaft journaled in said entrance, and a gear on the inner end of said shaft meshing with the gear in said supplemental housing.

3. In combination with. a power transmitting shaft, a gear housing in which it is journaled, and from which it protrudes and a coupling fast on theprotruding end of 3 said shaft; a gear fast on the protruding fgear portion of the shaft back of the coupling;

a sup lemental housing secured to the mam ousing and inclosing said gear, 'said housing having "a. lateral entrance leading into the housing cavity; a shaft j oui'naled in said entrance, and a gear on the inner end of said shaft meshing with the gear in said supplemental housing, the coupling comprising a sleeve or hub portion which is 1on gitudinally positioned by the gear in the supplemental housing, and said supplemen- 40 tal housing having a sleeveor hub exten sion which constitutes a journal'bearing for the sleeve or hub of the coupling.

1-. In combination with a power-transmitting shaft, a gear housing in which it is journalcd, and from which it protrudes; a

coupling fast on the protruding end of said I ing having a sleeve or hub extension which 6Q constitutes a journal bearing for the sleeve or hub of the coupling; the supplemental housing having a wick pocket opening into theh'ousing cavity inthe plane of the gear therein for holding a' lubricatingwickfin contact with said gear in the housing.

In testimon whereof, I have hereunto set m handat hicago, Illinois, this 24th day' 0. June, 1916,
